Voicemail Emails are not being sent for one Call Queue

[Aegis PS]

We are having an issue where one of our call queues is not receiving voice message email notifications. We have determined that this is only happening with one particular email box as changing it to another email box will work. A message trace has told us that the notification is not arriving to o365. The email box is completely functional otherwise. We would like to keep using the same email and would like to know why this has happened to avoid similar issues in the future.
Has anyone had this type of experience and know how to resolve this?

Thank you,

Are you using 3CX SMTP?
Is it possible a message to that address bounced in the past 7 days?

We are using 3CX SMTP. It is possible that a message bounced to that address. How would we resume alerts in that case?

Then it gets auto-banned for 7 days.
Either wait out the 7 days or contact support (they may or may not be able to remove it from the banned list).
